Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Initial climb
First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
Total loss of engine power (non-mechanical)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative

The World War II vintage airplane's engine experienced a total loss of power shortly after takeoff. During the forced landing, the airplane collided with electrical power lines and the ground. The pilot said the airplane's engine had been experiencing vapor lock problems in the past and that the engine had quit in the same manner as before. The airplane's fuel tank had leaked about 25-gallons of fuel on the ground after the accident had occurred. According to the pilot, the airplane's side cowling assemblies were taken off when the outside air temperature (OAT) exceeded 45-degrees Fahrenheit. This was supposed to eliminate the vapor lock potential. The OAT on the day of the accident was 80- degrees Fahrenheit. The airplane's side cowling had been removed before the accident flight. No other mechanical anomalies were found that would identify why the engine experienced a total loss of power.

Probable cause

the pilot selected to operate the airplane with a known deficiency. A factor in this accident was the vapor lock experienced by the engine's carburetor.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
